What is beta current multiplier?
A; Is not a current multiplier it is merely an empirical number assign to a part to indicate its capability at a certain current. The value can vary from 10 to 200 for the same transistor depends on the current that is is suppose to carry.
Where is the menu button on the sony cdx fw700?
We all know it's a dumb question. The answer's even dumber! It's on the remote. That's right. There doesn't seem to be a "Menu" on the unit.
There are a lot of features that can't be accessed without a menu button, including setting the clock and changing the display to show just the time instead of cycling through display options.
What is the major difference between positive and negative feedback?
Positive feedback causes bodily processes to continue; negative feedback causes bodily processes to start or stop

What does tablet friendly mean?
Tablet Friendly means that the (program) can work on on a tablet smoothly.
What causes a battery to reverse polarity?
Discharging it to 0V (ie. absolutely empty). And not battery, but "cell" (even a small AA or AAA battery is consider a "cell" - think Duracell).
Batteries are usually made up of individual cells (like car batteries, RC batteries etc.), and even if not all of them are discharged completely, if even just one cell reverses polarity, it will do irreversible damage to the battery.
How many data lines are necessary in 16-bit microprocessor?
It depends. From the CPU's point of view, 16 data lines are necessary in a 16-bit microprocessor. Some implementations, however, such as the 8088, use an 8-bit bus, instead of like the 8086, which uses a 16-bit bus. The Bus Interface Unit (BIU) handles the conversion, packing, and unpacking transparently to the Execution Unit (EU or CPU).
What is the 2 models of an iPad?
The 2 models are Black and White but you can get the IPad 2 in 16gb 32gb or 64gb in wifi or 3G.
Where can you buy DTS 7.1 surround sound?
Any store that sells surround receivers can sell 7.1 systems. All current models have both Dolby and DTS decoders.
What is meant by client-side processing?
Processing that is done on the client computer instead of the server computer. Most online multi-player games use client side processing to reduce server load and performance.
What is redundancy in an electronic system?
This refers to building or designing in to the equipment a number of systems that can "take over " if one part of the system fails to work. Some people call that a built-in back up system.
AnswerAs in a computer system, you would have 2 drives, both with the same exact information on them. When you write info to the drive or load a program on the one drive it loads it on the other drive. If one of those drives goes bad, all the info will be on the other drive and the system will continue to run. Of course you will want to replace the bad drive and copy good drive info to the new drive so that it is again a redundant system. AnswerRedundancy in an electronic system means to have components, which are critical in the working of a device, duplicated. This ensures a good amount of reliability in the working of system. So only critical components are duplicated and that too in applications like Space shuttle electronics or any other application whose operation is quite critical in itself.This makes sure that even if one of the redundant component fails another one will still be working to ensure the operation, however it might degrade performance but wont stop the working.
AnswerRedundancy can also refer to logic systems. This is when two or more logic gates cancel each other out and become unnecessary, for example two NOT gates in a row would be pointless, therefore they are redundant and can be removed. This is a common technique used to reduce the components in a system, and is a technique often applied when doing replacement such as NAND replacement or NOR replacement. However...Some designs often feature a few NOT gates in a line, but are not removed. This is not seen very often these days, as it's a bit of a dodgy fix. It is simply used to create a time delay, so a signal doesn't arrive at its destination too quickly.REDUNDANCY is the art of making a system more reliable by allowing a redundant system to perform the same duty without failing the primary system How redundant can a system be built ? It will reach a point where any additional redundancy could make the primary system fail because of it. It a question of reliability
Answer
In smart plant Instrumentation sometime we use Redundancy feature. It is just like stand by. In automation sometime we make a logic in which when one PLC fails to work then another PLC will resume the process without affecting it. it is also applicable in case of field instruments in Chemical Process Plant, Power Plant etc.
Is Costco opening a warehouse or store in beirut Lebanon?
Recently a warehouse in the " Jnaah" area that called itself " Costco" with the same exact logo,but I'm not sure if it has a " legal: connection with Costco . This warehouse is a little more bigger than the other stores in the same area who specialize in bringing in products from the US from Costco to sell them here. What makes these stores a little popular here is the fact that they bring in strictly products of US origin or products that are sold in the US market. " Some" of these products can be found here but most of the rest are not imported by any entity or company ( local distributor). The location is in the neighborhood of the Iranian embassy however if you are coming from Beirut it will be close to the intersection that leads to the embassy but in the opposite direction ( towards Beirut)
March/12/2013, I just called Costco in the US and spoke with Cameron Douglas in the export section and he confirmed to me that they don't have any stores in Beirut, Lebanon.
Mr. Cameron Douglas phone number is: +1(425) 427-7386.
How do you we make solar electronic bell?
firstly you will need a solar cell 3V to power your electronic bell .after that you can make a 5Khz sine wave geneartor and connect it to solar cell and you should also use a timing and control circuit to cuttoff the bell after some time and when any one press the switch circuit energies and take the power from solar cell and alarm will start.
What drive is a computers hard drive?
Typicly, in a majority of PC's, The main drive of a computer, the default storage and boot location is the C:/ Drive.
You can See this on "My Computer" option.
Default Hard Drive: C:/
How do you fix recording noise on computer?
I believe it's a hardware issue because it's only present when I record my audio. It sounds like a buzzing sound and like I'm in a cave.
Do jailbreak means stealing or just copying?
Neither. It is circumventing the built in restrictions that prohibit you from downloading software from other than the approved source. It is a form of contract violation and, as such, deprives you of legal remedies due to malfunction and it could theoretically constitute a civil violation on that basis alone.
As far as stealing or copying that "unapproved" software, that is a separate issue. There is risk there as well, but the question did not ask that.
Who invented the Colossus code breaking computer?
Tommy Flowers of the British 'General Post Office' did the first proof of concept prototype. At that time the GPO had the most experience of switching circuits.
What is used in high intensity discharge lamp to create light?
High Intensity Discharge (HID) lamps are a type of arc lamp. An HID lamp is comprised of a "glass" arc tube filled with a gas and a metal salt. The tube is generally fitted with two tungsten electrodes. Current applied to the electrodes is initially conducted in an arc through the gas. This initial arc raises the temperature of the metal salt until it vaporizes. At this point, the arc is conducted by the vaporized salt, greatly increasing the light output and decreasing the electrical current consumed.
There are several types of HID lamps in current use:
Mercury-vapor
Metal-halide (MH)
Ceramic MH
Low Pressure Sodium-vapor
High Pressure Sodium-vapor
Xenon short-arc
Each chemistry offers a different mix of operating characteristics including light intensity, color temperature, color rendering index (CRI), energy efficiency, and lifespan. The "glass" from which the arc tube is made must withstand extremely high operating temperatures and is typically composed of translucent or transparent fused quartz or fused alumina.

How do you change the time on the Motorola EX124G?
I couldn't find any way to do it from the screen. So I pulled the battery out and waited a couple of minutes then put the battery back in.
Then I had the correct time.
Robotics would be a subset of electrical engineering. Perhaps you will interested in an electrical engineering degree, if that is the type of career that interests you. http://en.wikipedia.org/wiki/Electrical_engineering These are the guys who work on the space shuttle and build robots and stuff.
